WIND OW-SCREEN.

Specification of Letters Patent. Patented Feb. 20, 1917.

Application filed April 1, 1916. Serial No. 88,242.

To all whom it may concern:

Be it known that I, ADRIAN ST. G. GAR- MAN, citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Nindow-Screen, of which the following is a specification.

My invention consists of a window screen which is adjustable to windows of different widths, the construction of the same being hereinafter described, and the novel features thereof pointed out in the claims.

The invention is satisfactorily illustrated in the accompanying drawing, but the important instrumentalities thereof may be varied, as long as they are included in the scope of the claims.

Figure 1 representsa front elevation of a window screen embodying my invention.

Fig. 2 represents a similar elevation showing the screen in extended condition.

Fig. 3 represents a front elevation of the left hand portion of either of thefigures, showing the covering cap of the spring roller employed, being in open position ex posing said roller.

Fig. 4 represents a vertical section of a portion on line 4 i Fig. 1. I

Fig. 5 represents a top or plan View of a portion of the frame of the screen, in the present case, at the left hand thereof.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings.

1 designates a frame which is composed of the sections 2 and 3, the upper and lower horizontal members 4: and 5 of which are fitted to each other telescopically, whereby the frame is extensible and so may be varied according to thewidth of the window frame to which said frame 1 is fitted.

The upper and lower members 41 and 5 of the section 2 are connected by the vertical bar 6, in the present case, at the left end thereof, and to said bar and the adjacent portions of said members 4- and 5 are secured the ears or brackets 7 on which are mounted the end pintles of the spring roller 8, for the piece 9 of netting or equivalent material, which may be wound on and unwound from said roller 8, as well known in the art of insect or window screens.

The front face of the bar 6 is somewhat concaved or channeled forming a pocket, as shown in Fig. 5, to allow the spring roller to freely occupy the same.

and 11, and the vertical bar 12, to which latter and said members 10' and 11 the piece of netting 9 is securedopposite to that secured to the roller. 8, so as to move with said section 8. It will now be seen that the device may be fitted to a window frame of ordinary width, as in Fig. 1, or to one of greater wldth, as shown in Fig. 2. In the latter case, the netting may be drawn out taut say to the right by the bar 12, and so follow the movable section 3, and thereby completely .cover the open window as existing between the bottom rail 13 of the raised sash, and the window sill 1 1 allowing the sash to be lowered and raised back of the frame 1 without disturbing the latter in its connection with the side stiles of the window frame.

If the window is narrow as in Fig. 1, the excess of nettingwinds on the roller 8, and said netting remains taut.

In order to connect the device to either of the window frames the bar 6 has latches 15 pivotally mounted thereon, the same being adapted to hook on or engage pins 16 on the adjacent side sill of the window frame. The bar 12 has latches 17 pivotally mounted thereon, the same being adapted to hook on or engage with pins 18 on the adjacent side sills of the window frame, it being evident that by properly operating the latches 15 and 17 the device may be readily removed from the window frame.

In order to cover the spring roller and permit access thereto, I employ the channellike cap 19 which is connected with the ver tical side bar 6 of the frame 1 by the hinges 20, whereby said roller may be inclosed from without, as in Fig. 2, or rendered accessible as in Fig. 3, said cap when in closed position being held from opening by means of the latch 21- on said cap, and the pin 22 on the cross bar 6, the effect of which is evident.

In order to strengthen the connection of the telescopic members 1, 10, 15 and 11 of the respective sections 2 and 3 of the frame 1, the contiguous sides of each pair of said members are formed with tongues and grooves 23 and 24, as shown in Fig.4, said tongues sliding freely in said grooves in the movement of the section 3 and serving to sustain the respective members one on the other.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is:

1. In a horizontally-adjustable Window screen, a frame composed of laterally-movable sections fitted to each other telescopically relatively to the Width of the Window frame, the vertical side bars of the sections and the adjacent side stiles of the Window frame being provided on the exterior thereof with devices for securing the screen frame to said stiles on the outer faces of the latter, one of the side bars having therein a vertically-arranged channel, a vertically arranged spring roller in said channel, a

horizontally adjustable screen Which is connected with said roller and the side bar of the opposite section of the frame, and horizontally-extending brackets forming the bearing for said roller connected With the bar at the top and bottom of said channel,

2. In a horizontally adjustable Window screen, a frame composed of laterally-movable sections fitted to each other telescopically relatively to the Width of the Window frame, latches and pins respectively on the vertical side bars of the sections and the adjacent side stiles of the Window frame on the exterior thereof for securing the screen frame to said stiles on the outer faces of the latter, one ofthe side bars having therein a vertically-arranged channel, a vertically-arranged spring roller in said channel, a horizontally adjustable screen Which is connected With said roller and the side bar of the opposite section of the frame, and horizontally-extending brackets forming the bearing for said roller connected With the bar at the top and bottom of said channel.

3. In a horizontally adjustable Window screen, a frame composed of laterally movable sections fitted to each other telescopically relative to the Width of the Window frame, the vertical side bars of the sections and the adjacent side stiles of the Window frame being provided on the exterior thereof with devices for securing the screen frame to the stiles on the outer faces of the latter, one of the side bars having therein vertically arranged channel, a vertically arranged spring roller in said channel, a horizontally adjustable screen connected With said roller and the side bar of the opposite section of the frame, horizontally extending brackets forming the bearings for said roller connected With the top and bottom frame members of the adjacent section at the ends of said channel, and a channel-like cap hinged to the vertical side bar of one of said frames to inclose said roller.
